2000 Jeep Cherokee will just die while driving down the road

I was driving on the freeway and my 2000 Jeep Cherokee just died. I tryed to start it and it would just turned over acting like no gas was getting to it. After waiting a couple of minutes I tried starting it again and it started like nothing was ever wrong. It did it two more time on the way home. Please help! What's wrong with my Jeep?

Sounds like your factory alarm is having issuses. Did you take out the battery prior to this happening? Try resetting it. check trouble codes dont start the car only turn to positions on,off,on,off,on,off,on and then count the blinking engine light a longer pause means you've moved on to the next number, domit twice if you were unsure of your count then compare to your chilltons, but I bet it's the alarm

If it is, than diagnosis just became easier. Take it to a good auto parts store (IE Autozone) or dealer and they can scan the camputer and tell you the error code. Even if it won't start, they can read the old codes....

It sounds like it may be a fuel pump issue. Have someone cycle the key (on then off, without starting it) while you stand at the back of the Jeep. You should hear the fuel pump turn on (light buzzing, to high pitched whirr), then off if the Jeep isn't started right away.

When it acts up again, do this test, if you don't hear the fuel pump buzz, then it is suspect.

Also, how long has been since the fuel filter was changed?

If it's been over a year, change it and see if that improves things.

Okay, I am back again.

The only component I know of, that shuts a Jeep off while idling or driving 40mph down the road, is a bad crank sensor. Usually when it starts going bad, it will sporadically shut off, like yours does. Eventually, it will just die and the Jeep will not start at all. Have it tested and replaced, if necessary.
